我正在使用Python创建一个小型设计器(使用PyGame)。 该程序只允许您放置图像,在图像之间进行更改,导出为PNG文件,以及将图像路径和坐标导出到文本文件中的放置位置。我已经使所有这些组件都能正常工作,但是我只能使用最后一个组件,那就是将文本文档读回PyGame,并使用正确的sprite将所有图像重新放置在正确的位置。
当我尝试从导出的文件之一中读取数据时,我目前拥有它的方式(已被重写且几乎可以使用)会产生错误。
错误当然是:
stamped_surface.blit(image, (xcrds, ycrds))
TypeError: invalid destination position for blit
这是我的代码:
import pygame as pg

from tkinter.filedialog import asksaveasfile
image_file = "../res/ExampleProject/TankGame/TankGameImg/tileGrass_transitionE.png"
f = open("../Saves/Backups/FailSafe.txt", "a+")
f.write("""

该程序具有文件系统和某些使事情发生的控件,因此它们是:
ESC KEY-自动导出程序以供参考和退出程序
S键-将Surface保存为PNG文件。
N键-提示用户选择要使用的新精灵
E键-使用文件提示符将图像导出到PNG
O键-打开包含坐标数据和图像路径数据的文件。
根文件系统的映像: https://i.imgur.com/KouhmjK.png
您应该了解的几件事: 该程序将每个文件位置自动保存到包含“坐标”和“图像路径”的文件中。
通过查看代码,文件系统相对简单,但是如果需要帮助,请询问。
答案 0 :(得分:2)
blits((source,dest,area),...))->(Rect,...)您错过了目的地。阅读here
如果您要使用坐标,请使用方括号[x-co,y-co] 像这样:
block.blit(image,[0,0])
